I've found riflegear in fountain valley to have really good service and deals specially in AR type rifles, a little pricey but have a large selection. Looking at picking up a Spike's tactical lower to start my AR build from them.
i've have good experiences with Turners in Fountain Valley and have purchased 4 firearms from them with in the past 3 months. Depends on who you get for service. I'm always in the store between 10am and 2pm and usually have no wait time to see a salesperson.
and yes shooting guns is expensive, so three of my friends and I are putting in $ for a Dillon XL650 as soon as grafs gives me access to dealer pricing.
